Global Metabolite Profiling: The Fast-Track for Functional Genomics
Posted May 11, 2011
Every metabolic process leaves behind a chemical footprint—a record of the reactions that occurred and the substances that entered or exited each cell. Of course, this footprint is transient, lasting only until other metabolic processes leave their own mark on enzyme, lipid, small molecule, and other metabolite levels. Metabolomics aims to exploit the temporal and spatial specificity of metabolic footprints to characterize disease states, identify biomarkers of risk and progression, predict treatment response, illuminate disease etiology, and, on a more fundamental level, understand the complex processes and components of metabolism.
Global metabolite profiling offers the breadth and the temporal and spatial specificity to elucidate underlying mechanisms of disease pathology and to advance understanding of multi-faceted conditions such as chronic pain and multiple sclerosis. On February 11, 2011 the New York Academy of Sciences held Global Metabolite Profiling: The Fast-Track for Functional Genomics, a forum for researchers in metabomics to discuss the latest discoveries in and the future of the field. Presenters covered applications of metabolomics methods to validating functional assignments for orphan enzymes, to identifying biomarkers of breast cancer development, and to everything in between. The symposium revealed the great strides that have already been made through studies of metabolites, the complex output of an even more complex set of regulatory interactions.

Steven Gross, PhD
Steven S. Gross is Professor of Pharmacology and Director of the Mass Spectrometry Core Facility. Gross's expertise is in pharmacology, and cell and structural biology, particularly in relation to the role of nitric oxide (NO) as a signaling molecule. In the late 1980s, Gross and colleagues made the initial identification of L-arginine as the precursor of NO in blood vessels. They were also first to establish that NOS inhibition elevates blood pressure in animals, demonstrating that NO plays a physiological role in controlling blood pressure and vascular tone. Since then, research efforts have predominantly focused on elucidating the enzymes and mechanisms that regulate NO synthesis in cells. Gross has authored or coauthored more than 90 research publications and 40 book chapters, review articles and books in the area of NO biology. He is an active member of NIH Study Sections and is a founder and Board Director of the Nitric Oxide Society, a group that organizes the major annual international meetings on the subject of NO and publishes a peer-reviewed scientific journal with novel reports on NO biology and chemistry. Gross received his PhD in Biomedical Science from the Mount Sinai School of Medicine in New York City.

Alan Saghatelian, PhD
Alan Saghatelian grew up in southern California and attended UCLA as an undergrad where he graduated with a degree in chemistry. He got his first taste of research working with Professor Craig Merlic in the area of organometallic chemistry and synthetic chemistry. For graduate school, Saghatelian attended The Scripps Research Institute in La Jolla where he moved into biochemical problems such as the molecular mechanisms that spawned life and allosteric regulation of enzymes through protein engineering. It was at TSRI that Saghatelian became more interested in biomedical research and he remained at TSRI for a postdoc with Professor Benjamin Cravatt where he developed (with Gary Siuzdak's help) methods for global metabolite profiling of lipids to identify novel mammalian lipids and substrates for enzymes. In 2006, Saghatelian started in the chemistry department at Harvard where he has continued to extend the utility of these methods to biology. He is currently an Associate Professor of Chemistry and Chemical Biology.

Gary Siuzdak is Director of the Scripps Center for Metabolomics and Professor of Chemistry and Molecular Biology at The Scripps Research Institute in La Jolla, California. He is also Faculty Guest at Lawrence Berkeley National Laboratory and served as Vice President of the American Society for Mass Spectrometry. His research includes developing novel approaches to unbiased metabolomics, the development of nanostructure-based platforms for mass spectrometry imaging, novel approaches to virus characterization and inhibition, and mass-based inhibitor-enzyme screening. He has over 170 peer-reviewed publications and two books, the latest being The Expanding Role of Mass Spectrometry in Biotechnology, 2nd Edition 2006.
Nicola Zamboni, PhD
Nicola Zamboni is a principal investigator at the Institute of Molecular Systems Biology of ETH Zurich since 2005. He graduated in group of Jay Bailey at the Institute of Biotechnology of ETH Zurich, where he also received his PhD in 2003 in the field of Metabolic Engineering. In 2004, he moved to Stanford University to devise metabolomics-derived approaches for unraveling causes of intracellular metabolic changes. His research in this area continues currently at ETH Zurich, where his work builds on metabolomics, 13C flux analysis, and computational biology.
Research in his group ultimately aims at identifying interaction networks involving metabolism in complex systems, spanning from microorganisms in natural environments to pathogens and higher cells.
